Chief Policy Counsel, Council on Criminal Justice and Senior Advisor, Right on Crime
Marc A. Levin is the Chief Policy Counsel for the Council on Criminal Justice (counciloncj.org) and Senior Advisor for Right on Crime.
An attorney and accomplished author on legal and public policy issues, Marc began the Foundation’s criminal justice program in 2005. This work contributed to nationally praised policy changes that have been followed by dramatic declines in crime and incarceration in Texas. Building on this success, in 2010, Levin developed the concept for the Right on Crime initiative, a TPPF project in partnership with Prison Fellowship and the American Conservative Union Foundation. Right on Crime has become the national clearinghouse for conservative criminal justice reforms and has contributed to the adoption of policies in dozens of states that fight crime, support victims, and protect taxpayers.
In 2014, Levin was named one of the “Politico 50” in the magazine’s annual “list of thinkers, doers, and dreamers who really matter in this age of gridlock and dysfunction.”
Marc has testified on criminal justice policy on four occasions before Congress and has testified before legislatures in states including Texas, Nevada, Kansas, Wisconsin, and California. He also has met personally with leaders such as U.S. Presidents, Speakers of the House, and the Justice Commtitee of the United Kingdom Parliament to share his ideas on criminal justice reform. In 2007, he was honored in a resolution unanimously passed by the Texas House of Representatives that stated, “Mr. Levin’s intellect is unparalleled and his research is impeccable.”
Since 2005, Marc has published dozens of policy papers on topics such as sentencing, probation, parole, reentry, and overcriminalization which are available on the TPPF website. Levin’s articles on law and public policy have been featured in publications such as the Wall Street Journal, USA Today, Texas Review of Law & Politics, National Law Journal, New York Daily News, Jerusalem Post, Toronto Star, Atlanta Journal-Constitution, Philadelphia Inquirer, San Francisco Chronicle, Washington Times, Los Angeles Daily Journal, Charlotte Observer, Dallas Morning News, Houston Chronicle, Austin American-Statesman, San Antonio Express-News and Reason Magazine.
In 1999, Marc graduated with honors from the University of Texas with a B.A. in Plan II Honors and Government. In 2002, Marc received his J.D. with honors from the University of Texas School of Law. Marc was a Charles G. Koch Summer Fellow in 1996. He served as a law clerk to Judge Will Garwood on the U.S. Court of Appeals for the Fifth Circuit and Staff Attorney at the Texas Supreme Court.

Partner, Crowell & Moring

With a decade of Justice Department experience managing the legal defense of all EPA rules, Mr. Lorenzen has a unique ability to help clients shape environmental policy, provide vital input on proposed federal environmental regulations through written comment and direct interaction with regulators, and mount effective judicial challenges to EPA actions that adversely affect his clients' interests.

EPA, in which the court upheld EPA's first suite of greenhouse gas regulations (largely upheld by the Supreme Court in Utility Air Regulatory Group v. EPA); EME Homer City Generation, L.P. v. EPA and North Carolina v. EPA, in which the court reviewed EPA's various attempts to address interstate transport of air pollutants; numerous cases challenging EPA regulations governing emissions of hazardous air pollutants; and National Cotton Council v.
